Physics 11 Gravitation Universal - Class 12 Boards Physics

## Universal Law of Gravitation and Principle of Superposition The universal law of gravitation describes the attractive force between two masses due to their mass and the distance between them. The principle of superposition states that the net gravitational force on a body is the vector sum of the gravitational...

What is the force of attraction due to a hollow spherical shell of uniform density on a point mass situated inside it?

Zero

Can a body be shielded from gravitational influence by any means?

No, it cannot be shielded

What is the force of attraction due to a hollow spherical shell of uniform density on a point mass situated inside it?

Zero

Can a body be shielded from gravitational influence by any means?

No, it cannot be shielded

Can a body be shielded from gravitational influence?

No, a body cannot be shielded from gravitational influence. This is because gravitational force is independent of the intervening medium.

What is the gravitational force inside a hollow spherical shell of uniform density?

The force of attraction due to a hollow spherical shell of uniform density on a point mass situated inside is zero.
